What is an electro -surgical unit?

typically consisting of an electric generator and one or more electrodes, an electrosurgical unit is often used in heating bodies to prevent blood loss. The machine can be used in the operating room or during an outpatient procedure. It is generally used for coagulation of blood vessels, thermal tissue and cut, all by means of high -frequency electric current. Common electrosurgical procedures include dermatological, backbone, cardiac and orthopedic surgery; To avoid burns, a contact back pad, ground pad or conductive gel is usually used during the procedure. The back -electrode monitoring system can also be used to turn off the system if the current becomes high enough to burn the patient.

The electro -surgical unit, first used in the 20th century, generally includes the main generator, electrode shoulder blades and needles, switches and controls of hands or legs. With a machine in a bipolar configuration, to connect two Gene electric polesThe rator uses the pliers type through tissue. Patients treated with a machine in a monopolar configuration often lie on a metal plate or plastic pad that connects to the return electrode. Surgeons usually make contact with one pointed probe on the heating of the localized area.

In low power operation, the electrocurgical unit is sometimes used without a back electrode; The human body usually has the ability to create a return path for current. Electrosurgical devices can be used to cut, which is usually done by evaporation of water and by applying high voltage with a fine wire. Coagulation often requires less heat and can also be carried out by drying, during which even less heat is used to treat abnormalities under the skin. The electrode is usually activated in the air just above the tissue during a full -length, which affects a relatively wider area on the skin surface.

the wool -formular used electrochirThe urgic unit may vary depending on the procedure. Energy can also be pulsated and the current on and off is often adjustable. Most electro -surgical generators can operate at 500 Kilohertz up to 3 megahertz, so it is important to use proper use; Otherwise, burns may occur in the body parts far from the electrode site.

Electrosurgical unit can be used at frequencies of up to 100 kilohertz. Stimulation of nerves and muscle is therefore usually lower and does not cause discomfort. Otherwise, muscle spasms, pain and cardiac arrest may occur. When using electro -surgical devices properly, they usually cause safer operations and can minimize complications that occur with uncontrolled bleeding.
